Review on Lisle 43390 36Mm Wrench by Teo Alston

Works like clockwork. Perfect fit for my 2002 Chevy Silverado 2500HD 6.0L (Gas) fan clutch. I used it without the Lisle air hammer attachment, just the smoothing attachment. Yes, it needed more control to prevent slipping, but it still did the job. I guess Lisle doesn't guarantee it'll be done that way, but I'm not worried about how little I use it. I plan on buying a full set of these keys in the future, but this worked in a pinch and was a lot easier than doing it by hand with two different keys and not worrying about something not turning. After using them, you'll never want to do it manually again.
